In the unforgiving Yukon territory, Belle Haggerty faces a harsh reality: abandoned by her husband and soon after widowed. Desperate to survive, she sets out to find a new husband.

In Dawson City, wealthy miner Seth Kirby is on a routine supply run when Belle's unexpected marriage proposal takes him by surprise. Initially wary, their relationship starts as a marriage of convenience, but Seth's admiration for Belle's strength and determination grows. With marriage already on his mind, he sees in Belle a chance for companionship and stability, and he reluctantly embraces her offer.

As they navigate their forced proximity, the tension between them slowly transforms into a deeper connection. However, their newfound peace is shattered when a sinister presence targets Belle. Fear and tension grip their once-peaceful existence as the danger draws them closer together.

Now, Seth, driven by his growing love for Belle, must summon every ounce of his strength to protect her. As their friends-to-lovers relationship deepens and the threat looms ever closer, will Seth's efforts be enough to shield Belle from the encroaching menace, or will the darkness surrounding them tear their fragile bond apart?
